【摘要】 <正> 豫西黄土丘陵台地位于河南省西部,西邻陕西,北濒黄河,南与伏牛山区交错,东同黄淮平原接壤,地域上包括三门峡、洛阳、郑州三市的大部和平顶山、许昌两市的部分地区,共计21个县、市,总面积约24733km~2,总人口1128万。本区耕地面积1392.3万亩,占土地总面积的38％,在全省低山丘陵区中垦殖率最高,人均耕地1.23亩,比全省人均耕地数量略低。 本区地处西部黄土高原与东部黄淮平原的交接和过渡地带,在特定的自然环境条件下,形成了许多独具特色的黄土地貌类型,当前已成为河南省农业用地的主要类型之一。本文从分析区内黄土地貌特征、形成过程和发育演变趋势入手,针对土地利用现状、潜力和存在的问题,提出合理开发利用各种土地资源的有效途径。更多还原

【Abstract】 Loess is accumulatively distributed over loess hilly platform in western part of Henan Province,in which area covered by loess occupies 90% of the whole loess area in the province.This area lies in the transitional zone of loess plateau in the west and Huang Huai river alluvial plain, in which many distinctive geomorphologic types of loess were formed in this specific natural condition. Having been farmed for a long time,this area had become one of the major types of farmland in the province. Rate of reclaimation and cultivation ranked the first in the low mountainous hilly area in the province and the disaster due to soil loss is very serious.Through analysing the characteristics of the loess geomorphology,the formation process and developing tendency of the loess,and in the light of present condition, potential capicity and pro blems existing in land utilization,the author proposes an effective approach to exploit and utilize all kinds of land resource reasonably.更多还原
